[OLEDp1-8] The challenge of OLED display quality in low gray scale
Sub-threshold swing , mura , color deviation, color deviation Compensation error of the pixel circuit
In this paper, two kinds of display defects under low gray scale are analyzed and we find the mechanism of the defect from the driving principle and TFT characteristics.
1. Vertical mura
2 . Color deviation
Finally, we summarizes the control standards for TFT characteristics in order to meet the display quality of AMOLED at low gray scale, and introduces the temporary measures for improving the problems mentioned using display system
